You can find more information concerning this topic in at least two of the history databases. If you use the library homepage, select Databases, then select History as a subject. Under the history databases, I tried your question on America History and Life and JSTOR. Both of these databases have information about George Washington after the battle. You can also find information in library books by searching UNACAT and using George Washington as a subject. Please let me know if you need additional information.
